o Step 3: Even lighting

The idea is everything that our lights generate as white will be the specularity. If you get really tricky with this method, you can create layers of specularity highlights by simply adjusting the rig. High-powered lighting will get you a sharper highlight. While lower level lighting will get you a more diffused spec.

O Step 4: Getting baked

We are going to pull a bake just like we would a regular projection. This time we'll enable "Bake Shading Group Lighting". Although this is a pretty proven way of doing specs, play around with some settings. Choke the Blinn's default color from grey to black and you get tighter specular highlights for layered specular shaders.
